Mercè Sitjà i Rabert is a PhD candidate at the Universitat Autònoma de Barcelona, Spain. We would like to acknowledge the contribution of Blanquerna School of Health Science (Universitat Ramon Llull) for their support to the first author, providing her a special leave to work on her thesis. We also thanks Tecnosport Condition SLU (Badalona, Spain) to give the Power plate vibration platforms for this study (Model Pro5 Airdaptive, Power Plate®) and Ms.Carolyn Newey (Institut de Recerca de l’Hospital de la Santa Creu i Sant Pau, Barcelona) for help in the editing process of the manuscript. This study is funded by the Institute for Older Persons and Social Services (IMSERSO), Spanish Ministry of Health, Social Policy and Equality, Project 180/ 2010.

N2 - Background: Institutionalized older persons have a poor functional capacity. Including physical exercise in their routine activities decreases their frailty and improves their quality of life. Whole-body vibration (WBV) training is a type of exercise that seems beneficial in frail older persons to improve their functional mobility, but the evidence is inconclusive. This trial will compare the results of exercise with WBV and exercise without WBV in improving body balance, muscle performance and fall prevention in institutionalized older persons. Methods/Design. An open, multicentre and parallel randomized clinical trial with blinded assessment. 160 nursing home residents aged over 65 years and of both sexes will be identified to participate in the study. Participants will be centrally randomised and allocated to interventions (vibration or exercise group) by telephone. The vibration group will perform static/dynamic exercises (balance and resistance training) on a vibratory platform (Frequency: 30-35 Hz; Amplitude: 2-4 mm) over a six-week training period (3 sessions/week). The exercise group will perform the same exercise protocol but without a vibration stimuli platform. The primary outcome measure is the static/dynamic body balance. Secondary outcomes are muscle strength and, number of new falls. Follow-up measurements will be collected at 6 weeks and at 6 months after randomization. Efficacy will be analysed on an intention-to-treat (ITT) basis and 'per protocol'. The effects of the intervention will be evaluated using the "t" test, Mann-Witney test, or Chi-square test, depending on the type of outcome. The final analysis will be performed 6 weeks and 6 months after randomization. Discussion. This study will help to clarify whether WBV training improves body balance, gait mobility and muscle strength in frail older persons living in nursing homes. As far as we know, this will be the first study to evaluate the efficacy of WBV for the prevention of falls. Trial Registration. ClinicalTrials.gov: NCT01375790.
